templates.asymmetric_encryption_scheme¶

Generic classes used for creating an asymmetric encryption scheme.

Attributes¶

`PK`
`SK`

Classes¶

`PublicKey`	Public Key of an AsymmetricEncryptionScheme.
`SecretKey`	Secret Key of an AsymmetricEncryptionScheme.
`AsymmetricEncryptionScheme`	Abstract base class for an AsymmetricEncryptionScheme.

Module Contents¶

class templates.asymmetric_encryption_scheme.PublicKey[source]¶

Public Key of an AsymmetricEncryptionScheme.

This should be subclassed for every AsymmetricEncryptionScheme.

class templates.asymmetric_encryption_scheme.SecretKey[source]¶

Secret Key of an AsymmetricEncryptionScheme.

This should be subclassed for every AsymmetricEncryptionScheme.

templates.asymmetric_encryption_scheme.PK[source]¶

templates.asymmetric_encryption_scheme.SK[source]¶

class templates.asymmetric_encryption_scheme.AsymmetricEncryptionScheme(public_key: PK, secret_key: SK | None, *_args: Any, **_kwargs: Any)[source]¶

Abstract base class for an AsymmetricEncryptionScheme.

classmethod from_security_parameter(*args: Any, **kwargs: Any) → Self[source]¶

Generate a new AsymmetricEncryptionScheme from a security parameter. Note that regular arguments will be passed to the generate_key_material method, so all parameter that are required for the constructor should be passed as keyword arguments.

Parameters:

*args – Security parameter(s) for key generation.
**kwargs – Security parameter(s) and optional extra arguments for the constructor.

Raises:

ValueError – If a keyword argument is not valid for key generation or the constructor.

Returns:

A new EncryptionScheme.

classmethod generate_key_material(*args: Any, **kwargs: Any) → tuple[PK, SK][source]¶

Abstractmethod:

Method to generate key material (PublicKey and SecretKey) for this scheme.

Parameters:

*args – Required arguments to generate said key material.
**kwargs – Required arguments to generate said key material.

Returns:

Tuple containing first the PublicKey of this scheme and then the SecretKey.

property public_key: PK[source]¶

PublicKey of this instantiation of the scheme.

Returns:: PublicKey of this instantiation.

property secret_key: SK | None[source]¶

SecretKey of this instantiation of the scheme.

Returns:: SecretKey of this instantiation, or None when it is unknown.
